"My baby girl started school today. I was extremely proud of her!" Messer wrote on her Instagram page, along with a few photos of Adalynn at school. "Mommys #BigGirl now! I always said I would wait until all my girls were in school and then I would go. It's finally that time to finish what I want to pursue in my career and start the college life as a mom of 3. #BitterSweet #schoolgirls #AAA #shesthebest #MyBaby is growing up! I'm so #Blessed!"
